Abstract
The ionosphere of Mars is infused with magnetic fields generated by the interaction of the solar wind with the ionized and neutral gas of the atmosphere. The magnetic fields measured by the magnetometer onboard the Mars Atmosphere and Volatile EvolutioN (MAVEN) spacecraft exhibit spatial and temporal variations (i.e., structures) with scales ranging from the global/planetary down to small scales of just a few kilometers. The magnetic field in some of these structures is such that it does not exert a force on the fluid (i.e., so-called force-free structures) and this study explores how this might happen.
Description
The paper that this material accompanies is primarily theoretical, but it does include some NASA MAVEN data in some the figures illustrating the theoretical results. All the MAVEN data can be found in NASA’s Planetary Data System (PDS) but the material in the KU repository provides the data in the form needed for some of the Figures. Much of the data comes from MAVEN’s orbit 3087. It is collected in an excel spreadsheet (both data and Figures). In addition, powerpoint files are provided, for convenience for two schematics in the Paper (Figure1 and Figure 12).
